Hello guys. I'am trying to place spheres on top of bifrost particles. Scattering goes ok if i do it through instancing or copier, but if i want to set for my spheres random size they start changing their size from frame to frame. is it any right way to do that? from my side i think i do it wrong.

I use this trick to keep random assigned values on the copier node from popping form frame to frame. I use the point Cloud to mesh node to assign each point to a specific vert(I find even with many particles this doesnt take very long to do.)Then I plug that into the Mesh2Array node to assign a random float to each vert(make sure type is set to mesh Vertex) then I connect the random float or vector to the Copier scale inputps sorry for my drawn connection in my screen grab i forgot to make it before it took it
